A video about DJ Pain1 ranting time signatures on twitter. There are people who believe you can't do fast hi hats or snappy snare rolls in single time (48-117 bpm). So the newer producer believe it's "easier" to achieve it in double time (120-160bpm ish??). There are tools in your DAW that allows it to be possible. Example, in FL Studio you can use the ctrl (command on MacOSX)+ U or Alt + U. Also, you can use the paint tool brush "B" inside the piano roll. In Ableton, you can use ctrl + 1,2, or 3 (or command + 1,2, or 3). Which method do you use? Please let me know in the comments.
